To reduce the reflection efficiency of the grating is the basic task during the design and fabricating process. Due to the speciality of the Brewster angle, the polarization light which propagates at Brewster angle can reduce the reflection efficiency. In this paper, the physical model of this kind of scheme is introduced, and the strict coupling wave method is used to calculate the optical character of the transmission grating under the Brewster angle. The results show that if the angle of incidence is chose to Brewster angle when the grating period is 2.80μm(wavelength is 0.35 μm), the reflection efficiency of the grating is restrained. For the short cycle grating(period is 0.21 μm), the highest 1 order diffraction efficiency of the transmission beam can be at depth of 3.50 μm, and t
